How to show a BITMAP under win98

25-Oct-02 1:43

If you use VC7 with MFC than you have a very handy class called CHtmlEditView which provides just what it promises: simple Html editing capability.

Hi,

I try to show a bitmap in my dialog based app. using the static control. I use this code:

CBitmap bmp_1;
bmp_1.LoadBitmap(IDB_BITMAP_1);

m_Bmp.SetBitmap(bmp_1);
m_Bmp.Invalidate();
UpdateData(FALSE);

This works good under Windows XP but not under windows 98.

What do i wrong??

Thnks

How can I create an non Modal Dialog (CColorDialog, CFontDialog,...)

Thank You a lot!

Hi Nishant!

I think the problem to create a NON MODAL CColorDialog, CFontDialog, ... is that there is no template id for the Create(...) function! The DoModal() function of this dialogs will end in an API call!

CModeLess *m_pmodeless = new CModeLess(this);
m_pmodeless->Create(CModeLess::IDD);
m_pmodeless->ShowWindow(SW_SHOW);

For CColorDialog or CFontDialog there is no IDD!

Here is a rather sneaky way of showing a modeless color dialog :-

//Use it at your own risk
void CYourDlg::OnBnClickedButton1()
{
	CHOOSECOLOR cc;                 
	ZeroMemory(&cc, sizeof(CHOOSECOLOR));
	static COLORREF acrCustClr[16]; 		
	cc.lStructSize = sizeof(CHOOSECOLOR);
	cc.hwndOwner = NULL;
	cc.lpCustColors = (LPDWORD) acrCustClr;	
	cc.Flags = CC_FULLOPEN | CC_RGBINIT;	 
	ChooseColor(&cc);
}

Thanks! Realy good! I didn't remember that there is a owner member in the CHOOSECOLOR struct! Smile | :)

Serial port communcations? I will spare the code for now but I'm having a problem I cant finger out. Not sure if overlapping will help either. I'm new to serial comm routines... If you think you can help send an email to mfeik@comporium.net. If you would like to look at my code I'll send it.. I thought this was going to be a simple dialog box interface but my reads are not proving this to be the case

There is a serial MFC class here (somewhere, sorry I'm to lazy to search the link). I used it to communicate with a microcontroller once and exchange data, it worked well.

i used several years ago, i can't remember everything, but:

u must use overlapped, must use EV_CHAR and EV_EMPTY 2 events.

you don't happen to remember WHY I must use overlapped do you? I have a serious problem with what I thought was going to be a simple app.

Good implementation ??? (struct, STL vector)

Any chance you have a little time you might be able to lend me? I have a program that I'm having problems with. I'll leave the details dependent upon your response.

Question about Dlls

CEx24-Oct-02 21:54

Lets say I have two extension dlls Dll1 and Dll2 and an Application MyApp. Now following is the scenario.

Dll1 uses Dll2.
MyApp requires Functions from Dll1 and some functions from Dll2.

Now the question(s)

1) In case of Extension Dlls , where does this Dll gets loaded? withing the memory space of MyApp ? or outside the memory space of MyApp ?

2) Since Dll2 is used twice , a) directly from MyApp, 2) indirectly through Dll1. So is it going to cost any how on performance ? in terms of memory or any other way ?

If yes then what should be the alternative ?

No, the OS uses memory mapping. Each DLL is loaded once into a global memory space and then the required DLL memory is mapped onto the applications process space. So no matter what you do each DLL will only ever be loaded once.

I have to implement a list that stores 2 strings and a pointer.
I have created a struct that hold this things:

struct TEST
{
    CString s1;
    CString s2;
    int*    pInt;
};

The struct holds the 2 strings and a pointer.
(CString because it's easy to handle in UNICODE and non UNICODE systems)

As next I have created a list with the STL vector class:

vector<TEST> myArray;

So, I can work very simple with my struct (example):

for (...)
{
    TEST t;
    t.s1   = _T("string 1");
    t.s2   = _T("string 2");
    t.pInt = NULL;

    myArray.push_back(t);
}

Do you think it's a good implementation or is there something I could do better (memory, make something faster, ...) ???
